Operator-Guided Invariance Learning for Continuous Reinforcement Learning

Researchers propose VPSD-RL, a reinforcement learning framework that discovers value-preserving structures in continuous control tasks using Lie-group operators and diffusion models. The method improves data efficiency and robustness by identifying nonlinear transformations that preserve optimal value functions, addressing brittleness in RL systems under environmental variability.

Discovering Symmetry Groups with Flow Matching

Researchers introduce LieFlow, a machine learning framework that automatically discovers symmetries in data by treating symmetry discovery as a distribution learning problem on Lie groups. The approach can identify both continuous and discrete symmetries within a unified framework, significantly outperforming existing methods like LieGAN in experiments on synthetic and real datasets.
